WILLIAM D. LOWRY, OF ST. LOUIS, MISSOURI.

METALLIC RAILWAY-TIE.

Application filed January 11, 1908.

Specification of Letters Patent.

Patented.Sept. 15, 1908.

Serial No. 410,356.

To all whom it may concern:

Be it known that I, WILLIAM D.LOWRY, a citizen of the United States of America, residing at the city of St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Metallic Railway-Ties, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to metallic railway ties and it has for its object the production of skeleton railway ties of this description so made as to diminish the number of ties necessary in a railway for the proper support of the rails and also at the same time provide more eflioient supports for the rails.

Figure I is a perspective view of a section of railway track having my improved ties therein. Fig. II is an enlarged top or plan View of portions of two adjoining railway ties constructed in accordance with my invention, and a section of railway rail mounted thereon. Fig. III is an end elevation of one of the ties shown in Fig. II and a fragment of the adjoining tie. Fig. IV is a vertical cross section taken on line IV IV, Fig. III. Fig. V is a vertical section taken on line VV, Fig. IV. Fig. VI is a vertical cross section taken on line VIVI, Fig. III. Fig. VII is a view similar to Fig. II illustrating a modification. Fig. VIII is a view similar to Fig. III illustrating the modification shown in Fig. VII. Fig. IX is a side elevation of one end of one of the ties shown in Figs. VII and VIII.

In the accompanying drawings: A designates railway rails shown supported by my railway ties.

1 designates skeleton metallic ties which are of bridge and channel shape the central portions being elevated above the outer foot portions 2. The channels of the ties are located at their upper sides and the webs at the bottom of saidchannels are provided with parallel-longitudinal slots or openings 1 and strengthened by longitudinal reinforcing ribs 3. It will be apparent that inasmuch as the webs of the channels are at the bottoms of the ties the road bed material of the railway may be readily tamped beneath the elevated central portions of the ties to firmly embed them in such road bed material. To provide against slipping of the ties in a lateral direction relative to the ties and longitudinal direction relative to the railway track, I produce at the bottoms of the foot portions of the ties parallel longitudinal fins 4, see dotted lines Fig. I and full lines Figs. III, IV and VI.

5 designates skeleton cross arms extending laterally from the ties and the top surfaces of which are disposed flush with the railway rail receiving seats of said ties in order that the railway rails may rest upon said cross arms in conjunction with the ties. These cross arms may extend to any desired length and they serve to assist the ties in the support of the railway rails and as a consequence make it possible to employ a lesser number of railway ties in a railway in view of the fact that the ties may be spaced more widely apart than they commonly are. The cross arms 5 are preferably constructed with base flanges 6, see Figs. I, II, III, V and VI, vertical webs 7, top webs 8 and end webs 9, see Figs. I and IV. The adjacent cross arms of the adjoining ties may be connected to each other bybolts 10, as seen in Fig. V. For the purpose of separating the cross arms of the ties from each other and providing for the insulation of these cross arms where it is desirable for electrical purposes I interpose between the adjacent cross arms distance pieces 1 1 that may be of non-conducting material when necessary and may be used in any desirable thicknesses to separate the cross arms to greater or lesser degree. It is obvious that the distance pieces may be employed to advantage in a curved section of railway track for the purpose of affording necessary separation of the cross arm to a greater degree at the outside of the curve than at the inside of such curve.

The ends of the ties are provided with pedestals 12, see Figs. I and III, which are located within the channels of the ties adjacent to the rail seats and at the upper ends of which are ledges 13 located beneath the rail seat faces of the ties. These pedestals serve as supports for sound deadening blocks 14 that may be of wood or other suitable material and which serve to lessen the noise incident to the passage of cars along the railway rails supported by my ties.

The railway rails are secured to my ties by bolts 15 that are seated in the top webs 8 of the cross arms 5, see Figs. I, II and VI, and they are further secured to the ties and held from lateral movement upon the ties by braces 16 and 17 and bolts 18 which pass through said braces and the railway rails.

The braces 16 are preferably formed integral VII to IX inclusive, the ties 1 are made of sectional form instead of being made in single pieces and the sections of said ties are united y rivets or bolts 1 which are seated in the central longitudinal ribs 3 of the ties. In this construction the laterally extending arms 5 are carried by the sections of the ties but it is obvious that when said sections are united the resultant ties corres 0nd in construction to the ties first descri ed and that their utility is the same as the first described ties. I11 this modification no provision is made for the connecting of the cross arms such as that furnished by the bolts 10, in the main form of the invention, and therefore 'the ties are merely placed together so as to be held u on a railway road bed in assemblage witi each other so that the ends of their cross arms will be in juxtaposition with each other without the cross arms being united.

The balance of the parts shown in the modification corresponding to that shown in the first described construction are designated by similar reference numbers having prime-marks or exponents.

I claim:

1. A metallic skeleton railway tie, of bridge and channel shape, constructed with an elevated central portion, a longitudinal rib extending centrally of the tie, foot portions, at the ends of the tie, and cross arms extending from the foot portions at each end of the tie.

2. A metallic skeleton railway tie, of bridge and channel shape, constructed with an elevated central portion, having longitudinal parallel slots, a longitudinal rib extending centrally of the tie, between the parallel slots, foot portions, at the ends of the tie, and cross arms extending from the foot portions at each end of the tie.

3. A metallic skeleton railway tie, of bridge and channel shape, constructed with an elevated central ortion, a longitudinal rib extending centra ly of the tie, foot portions, at the ends of the tie, having parallel longitudinal fins, and cross arms extending from the foot ortions at each end of the tie. 4. A meta lic skeleton railway tie, of

bridge and channel shape, constructed with an elevated central portion, having longitudinal parallel slots, a longitudinal rib extending centrally of the tie, between the parallel slots, foot portions, at the ends of the tie, having parallel longitudinal fins, and cross arms extending from the foot portions ateach end of the tie.

5. A metallic skeleton railway tie of bridge and channel shape, constructed with an elevated central portion, a longitudinal rib extending centrally of the tie, foot portions, at the ends of the tie, having pedestals formed with ledges, sound deadening blocks supported upon the ledges, and cross arms extending from the foot portions at each end of the tie.

6. A metallic skeleton railway tie, of bridge and channel shape, constructed with an elevated central portion, a longitudinal rib extending centrally of the tie, foot portions, at the ends of the tie, and cross arms, consisting of base flanges, vertical webs, top webs, and end webs and extending from the foot portions at each end of the tie.

7.

8, A metallic skeleton railway tie, of bridge and channel shape, constructed with an elevated central portion, a longitudinal rib extending centrally of the tie, foot portions, at the ends of the tie, and cross arms, consisting of base flanges, vertical webs, top webs, and end webs, provided with integral and detachable braces, and extending from the foot portions at each end of the tie.

9. A metallic skeleton railway tie, of bridge and channel shape, and divided its whole length, longitudinally, constructed with an elevated central portion, a longitudinal rib extending centrally of the tie, foot portions, at the ends of the tie, and cross arms extending from the foot portions at each end of the tie.
